big problem for work on passport!!!

hi!
I am using the docs to go on the PP to continue to edit the word file which I take it from the laptop. But I cannot save it on the phone. it said this software has no right to do it. I search the information about it. it said it is the personal space. there are two space on the phone. personal space and work space! something about the blackberry balance! so I don't know how to change my personal space to work space on the passport!!!
